Sencha.io is an entirely new way for the client developer to think about the cloud. To store data, you simply tell your model to store data. And it does the rest. If you need to send messages to other users, you enable messaging with just one line of code. If you need to listen for messages, just set up a callback. And Sencha.io does the rest. If you need to log users in from Facebook, you just request the login with an API, and Sencha.io automates the whole process. And if you need a place to deploy your application, Sencha.io provides that, too.
